vCenter server crashes in CustomizeVM_Task called for customizing ip settings

[bvivek]

Hi,

My objective is to customize ip settngs of a windows virtual machine adapter. Following is the code which I have written

CustomizationIPSettings adapter = new CustomizationIPSettings();  
adapter.dnsServerList = new String[] { "192.168.172.151"};   
adapter.gateway = new String[] { "192.168.172.1" };  
CustomizationFixedIp fixedIP = new CustomizationFixedIp();  
fixedIP.ipAddress = "192.168.172.113";   
adapter.ip = fixedIP;
adapter.subnetMask = "255.255.252.0"; 
CustomizationAdapterMapping adapterMap = new CustomizationAdapterMapping();  
adapterMap.adapter = adapter;
adapterMap.macAddress = "00:50:56:86:00:00"; 
CustomizationSpec customsSpec = new CustomizationSpec();  
customsSpec.nicSettingMap = new CustomizationAdapterMapping[] { adapterMap };  
customsSpec.globalIPSettings = new CustomizationGlobalIPSettings();  
CustomizationSysprep identity = new CustomizationSysprep();  
identity.guiUnattended = new CustomizationGuiUnattended();  
identity.identification = new CustomizationIdentification();  
identity.userData = new CustomizationUserData();  
identity.userData.fullName = "";  
identity.userData.orgName = "";  
identity.userData.productId = ""; 
CustomizationFixedName computerName = new CustomizationFixedName(); 
computerName.name = "test1"; 
identity.userData.computerName = computerName;
customsSpec.identity = identity;
// vCenter Server Crashes after this call
ManagedObjectReference taskmoref = service.CustomizeVM_Task(vmmoref, customsSpec);

After calling CustomizeVM_Task vCenter server crashes. Can somebody help me find the problem?

I doubt whether customsSpecs is initialized properly. But I do not know exactly whats wrong there.

Thanks,

Vivek.

vCenter Server did not crash after initializing identity.userData.fullName and identity.userData.orgName to non-empty strings. However as I doubted earlier CustomizationSpec is not initialized properly. Looks like, CustomizeVM_Task with CustomizationSpec may not be a good option to change IP settings of a virtual machine which is already in use. (That is, when the virtual machine is installed properly with all the necessary configurations). This is for two reasons- its slow and we need to provide additional information fore sysprep which is unnecessary and redundant for our task of changing IP settings. VIX apis could be a better option.

Please provide any comments on my understanding and better suggestions if any, for the task.

Thanks,

Vivek.
